“…consists of an efficient heat exchanger combining the CO 2 condenser with H 2 O evaporator. However, this reduces its possibility for direct use of a cooling tower to cool down the condenser in cold seasons, while sorption system itself can be applied for heating as a heat pump (Chen et al, 2010;Grzebielec, 2009;Starace et al, 2014;Wang et al, 2005;Ward et al, 1979). The concept of the presented system is the composition of the HT adsorption with LT compression cycle shown in Fig.…”

Searching for new refrigerants is one of the most significant scientific problems in refrigeration. There are ecological refrigerants commonly known: H 2 O and CO 2 . H 2 O and CO 2 known as natural refrigerants, but they have problems:a high freezing point of H 2 O and a low triple point of CO 2 . These problems can be solved by the application of a hybrid sorption-compression refrigeration cycle. The cycle combines the application possibility of H 2 O in the high temperature sorption stage and the low temperature application of CO 2 in the compression stage. This solution gives significant energy savings in comparison with the two-stage compressor cycle and with the one-stage transcritical CO 2 cycle. Besides, the sorption cycle may be powered by low temperature waste heat or renewable heat. This is an original idea of the authors. In the paper an analysis of the possible extension of this solution for high capacity industrial refrigeration is presented. The estimated energy savings as well as TEWI (Total Equivalent Warming Impact) index for ecological gains are calculated.

This work presents an application possibility of sorption refrigerators driven by low temperature fluid for air conditioning of buildings. Thermodynamic models were formulated and absorption LiBr-water chiller with 10 kW cooling power as well as adsorption chiller with silica gel bed were investigated. Both of them are using water for desorption process with temperature T des = 80 o C. Coefficient of performance (COP) for both cooling cycles was analyzed in the same conditions of the driving heat source, cooling water Tc = 25 o C and temperature in evaporator Tevap = 5 o C. In this study, the computer software EES was used to investigate the performance of absorption heat pump system and its behaviour in configuration with geothermal heat source.
